Persistent Currents in 1D Disordered Rings of Interacting Electrons
G. Bouzerar ; D. Poilblanc ; G. Montambaux ;
Date 5 Oct 1993
Subject cond-mat
AbstractWe calculate the persistent current of 1D rings of spinless fermions with short-range interactions on a lattice with up to 20 sites, and in the presence of disorder, for various band fillings. We find that {it both} disorder and interactions always decrease the persistent current by localizing the electrons. Away from half-filling, the interaction has a much stronger influence in the presence of disorder than in the pure case.
